a genre of music that is much like hardcore. it has a different style though, where it will be heavy then have a melodic breakdown.Also they scream much more than hardcore. Newer hardcore screams to but people who only like oldschool hardcore say thats fake hardcore.SO,post-hardcore consists of poety like lyrics, melodic break downs, emo choruses, and usually a emo-scene crowd.

When Hardcore and Punk mixed. Making the sound of Hardcore at some parts then slowing down for more punk parts with singing, not screaming. A band called "Refused" experimented with this. They were a Hardcore band. With the release of "The Shape Of Punk To Come" By "Refused" is when Post-hardcore was born. They thought they were changing punk, when they made a new genre. Doesn't confuse this with emo, or screamo.

It all starts with punk rock, see, and rock 'n roll. From rock 'n roll spawned a style of music called "hard rock" which is basically rock 'n roll but deeper. When hard rock is blended with punk rock, we get hardcore rock which essentially pre-emo punk rock with heavier rhythms. Also spawning from rock 'n roll and classical music we get metal. Now, when we blend hardcore with metal, we get "metalcore" which is hardcore but with harmony elements and the occassional guitar solo. Now it gets complicated. When we blend hard rock with metal, we get thrash metal. If we take thrash metal, add some more emo and myspace, and blend it with hardcore rock, we get "post hardcore" which can very very easily be confused with screamo. The main difference between post hardcore and screamo is that in post hardcore, the singer still "sings" but doesn't go into a crying fit at some point during the song. Now, there is one more style that is left un-discussed. A style called "hXc'mo" (prounounced "aytch ex see mo". I'm not quite sure, but I think that hXc'mo is the product of blending screamo and post hardcore...that's the only logical way I can figure this shit out.

Classifying post hardcore and all these different music genres was a real bitch.

The post hardcore genre developed from the hardcore scene in the USA in the late 1970's. Post harcore is based on the same structure as hardcore but with a few added creations such as beatdowns, blast beats and breakdowns.

The beatdown consists of a standard 4/4 rock beat which is played with a lot of aggresion so the song feels really powerful and edgy, the guitars are usually play chords or moderatly fast picking during this part of the song,the vocals in this part of the song could be screaming or singing.

A blast beat is usually used a pre-chorus or can be used as an intro or build up to a solo. for a blast beat the drums would be playing double bass while the snare and hi-hats would be played alternatly or two strikes on the snare for every one on the hi-hat at high speed while playing moderatly fast double bass, the guitars in this part of the song would be playing very fast alternate picking, the vocals during a blast beat are usually a very deep scream or roar.

In post hardcore the breakdown is probably the most powerful part of the song because this is generally the heaviest part. In a breakdown the drums would slow down into half time or even slower and would play a pattern on the bass drum usually with a lot of double which can be fast or slow which the guitarists would follow, the guitarists would follow the double bass pattern playing palm muted notes on the lower strings to make it really heavy. The vocals in a break down tend to go from a period of low screams to a period of higher screams which may be done by the one vocalist or going between two vocalists.

Some bands in this genre are

Here are some good post hardcore bands: I Killed The Prom Queen, Parkway Drive, As I Lay Dying, Norma Jean, Bleeding Through, Every Time I Die, Bring Me The Horizon, August Burns Red, All Shall Perish

a genre of music that has emerged out of harcore music and been compined with emo, pop, punk, etc. to become an unpredictable, whisper to scream style that is above all emotionally, lyricaly, and musicly honest.
